Can you give sources for the claim of how much diesel would be saved by an inflatable pad in the front and back?

Good question and one I’m curious to know as well. Parent said about “~halve” their consumption?

This is only partially related but this NASA article says with their aerodynamic technology a truck can save almost 7000 gal of diesel a year.

If we assume (just to get ballpark numbers) a semi gets about 5mpg and drives about 100k miles a year that’s about 20k gal of fuel.

Don’t truckers (at least in the US) often own their truck? I would assume that being more of a constraint than the aerodynamic tech itself
